Any savvy business owner understands that engaging a small, focused group of potential customers who have already expressed interest in their business is a typically effective way to target market. Most social media platforms allow professionals to have a free account or page with the option to add on demographic-driven advertising, which also has a good record for a satisfactory return on investment as long as the page's offerings are competitive with the niche market. Furthermore, over 75 percent of all internet users use social media.1 The potential to grow an audience and reach billions of users is endless.
